matches those of the various Mapper* interfaces. Without this, the
the destruction of the static cros_gralloc_driver `s_instance`
could race with a potential CrosGralloc4Mapper user on another
thread which is still alive at the time of exit() (for example,
a buffer being cleaned up on a libhwbinder worker thread).

get(<metadata>) will want to access metadata that may be
in either the buffer's handle or the buffer's reserved

dumpBuffers() where we need to iterate over all of the
buffers while holding a lock on the cros_gralloc_driver's
mutex.

Only a single cros_gralloc_driver instance is allowed to exist in a
process. However, currently when Gralloc3.0 or Gralloc4.0 is used, it's
possible for 2 independent driver instances to be created. This change
refactors cros_gralloc_driver to be a singleton and ensures the driver
initialization only happens once per process.

- buffer flushing
- buffer debugging (buffer listing and buffer id)
